I am a newbie to ColdFusion and Javascript. I am trying to perform validation on a coldfusion webpage before letting the user leave the page. The javascript is working however, after the alert is shown to the user the CF page errors because a url variable I passed loses its value. I use this command when I first enter the page <cfset variables.docnum= #url.docnum#>. How can I keep this value when the javascript returns? Any help would be appreciated.
